(a) Field of the Invention
This invention pertains to a kind of changeable imitation fur and linen face fabric and its processing technique.
(b) Description of the Prior Art
Following the continuous development of the knitting technology and the rise of living standards in recent years, consumers are demanding more from clothing fabrics such as color, feel, looks and function etc. To meet such demands, the development of multiple function face fabrics is already a course the knitting industry must take. Disadvantages of traditional composite fibers which this invention seeks to improve on are: limited single function and area of application, low grades, poor level of comfort, and low add-on value.
The objective of this invention is to provide a kind of imitation fur and linen face fabric with changeable effect. The advantages of this invention are soft tactility, abrasion resistant, good drapability, air permeability, flexibility, anti-static and anti-bacterial abilities.
To achieve aforementioned objective, the technical plan of this invention is as follows:
A kind of changeable imitation fur and linen face fabric is weaved by using warp and weft yarns with a weight ratio dependent on the required density. The warp yarn uses mixed spun yarn with bamboo polyester and fine polyester as raw materials. The weft yarn uses multiple color changeable yarn with allotropic and anisotropic yarn and adhesives as raw materials.
Aforementioned mixed spun yarn has a bamboo polyester and fine polyester weight ratio of 65:35 respectively.
Aforementioned allotropic and anisotropic yarn is composed of triangular polyester and positive ion polyester.
Aforementioned mixed spun multiple color changeable yarn has a triangular yarn, positive ion yarn, and adhesive weight ratio of 25:40:35 respectively.
The processing technique of a kind of changeable imitation fur and linen face fabric involves the following procedures: First, weave the warp and weft yarns together into grey fabric. Then, pass the grey fabric through turning, stitching, scouring, water extraction, stentering, pre-setting, dyeing, water extraction, stentering, and finished product setting to complete the process. A moisture absorbent anti-static agent is added to the aforementioned dyeing procedure. First, dilute the moisture absorbent anti-static agent into a 15% dispersing liquid. Let stand. Prepare dyeing liquid. Allow temperature of dyeing liquid to rise gradually to 55-65 degrees C. before adding anti-static agent. Raise the temperature to 70 to 90 degrees C., then slow down the rise of temperature to 115 to 125 degrees C. in 2 degrees C./minute increments. Maintain temperature for 40-50 minutes. Finally, lower the temperature to 60-80 degrees C. in 2 degrees C./minute increments to discharge liquid, then proceed to washing process.
Aforementioned pre-setting uses dry heat pre-setting procedure.
The beneficial effects of this invention are: By using a new yarn mixed spun from bamboo polyester and fine polyester, this invention aims to provide a kind of changeable imitation fur and linen face fabric that would overcome the disadvantages of traditional composite fiber products such as single-functioned, low fabric grade, poor product comfort level. limited area of application, and low add-on value. Moreover, the yarn used can reflect or cover the product from ultraviolet rays. It transforms the ultraviolet ray energy and breaks down bacteria and other pollutants to enable the product to absorb moisture, vent air, resist bacteria and ultraviolet rays. In addition, this new product features soft tactility, abrasion resistance, abundant patterns, distinctive lines, full structure, special luster, glittering effect, good drapability, air permeability, anti-static ability, and flexibility. It can satisfy consumer demands for functionality, comfortability, environmental protectiveness, hygiene, sanitation and health preservation.
Application 1:
The changeable imitation fur and linen face fabric referred herein as application 1 uses mixed spun yarn weaved from medium organzine bamboo fiber and fine polyester as raw materials. The weight ratio between medium organzine fiber and fine polyester is 65:35. The weft yarn uses multiple color changeable yarn mixed spun from allotropic and anisotropic polyester and adhesive as raw material. The allotropic and anisotropic polyester includes triangular polyester and positive ion polyester. The weight ratio of triangular polyester, positive ion polyester and adhesive is 25:40:35 respectively. After being wound by an automatic winder, the warp yarn passes through double twisting, setting, warping, and drawing-in processes. The weft yarn, after being wound by an automatic winder, passes through double twist, setting, assembly, and skein winding processes. The warp and weft yarns that had gone through the aforementioned processes are then weaved together into grey fabric.
The grey fabric is passed through the following steps to complete the entire processing technique: turning, stitching, scouring, water extraction, stentering, dry heat presetting, dyeing, water extraction, stentering, and finished product setting. Fiber tension must be well-controlled during the entire process. Imported ceramic system is used in the double twisting process to control tension while a circular tension machine is used in warping to maintain permanent tension. This ensures the tensile change of different raw materials is kept to the minimum.
In the dyeing procedure, first dilute the moisture absorbent anti-static agent into a 15% dispersing liquid. Then, prepare the dyeing liquid. Allow the temperature of the dyeing liquid to rise. When 60 degrees C. is reached, add the anti-static agent to the dyeing liquid. Raise the temperature to 85 degrees C. then subsequently slow down the rise of temperature to 120 degrees C. in 2 degrees C./minute increments. Maintain temperature for 45 minutes. Finally, lower the temperature to 75 degrees C. in 2 degrees C./minute increments to discharge liquid, then proceed to washing process.
